The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 5, the present embodiment provides an endoscope handle 100, where the endoscope handle 100 has a self-locking function, and the relative position of the rotating member 120 and the housing 110 is fixed by the self-locking function, so as to fix the motion posture of the active bending section, thereby solving the technical problem that the current endoscope cannot stably maintain the motion posture of the active bending section for a long time.

Specifically, as shown in fig. 2 to 5, in the present embodiment, the endoscope handle 100 includes a housing 110, a rotation member 120, a toggle member 130, a first stopper member 140, and an elastic member 150. The housing 110 is the mounting base for the various components within the endoscope handle 100, with the housing 110 having a mounting cavity therein for receiving the various components of the endoscope handle 100. The rotating member 120 is disposed inside the housing 110, and the rotating member 120 can rotate relative to the housing 110 through the rotating shaft 124, so that the circumference of the rotating member 120 is generally used to be connected with a traction wire, so that the traction wire can be wound on the rotating member 120 after the rotating member 120 rotates by a certain angle, thereby realizing the purpose of pulling the traction wire to move, and the traction wire is a main component for controlling the bending direction and angle of the active bending section of the endoscope, and the control of the bending direction and angle of the active bending section can be realized by pulling the movement of the traction wire. The stirring member 130 is a component in the endoscope handle 100 for controlling the rotation angle and the rotation direction of the rotating member 120, in this embodiment, a first through hole 121 is provided on the rotating member 120, the stirring member 130 has a proximal end and a distal end opposite to the proximal end, the proximal end of the stirring member 130 is located outside the housing 110, the distal end of the stirring member 130 is located in the housing 110, and the distal end of the stirring member 130 passes through the first through hole 121. Moving the toggle member 130 along the rotation direction of the rotation member 120 at the proximal end of the toggle member 130 can rotate the rotation member 120, thereby adjusting the bending action of the active bending portion of the endoscope; sliding the toggle member 130 along the axial direction of the first through hole 121 at the proximal end of the toggle member 130 can change the relative positions of the proximal and distal ends of the toggle member 130 and the rotating member 120. Through setting up the stirring piece 130 to can slide along first via hole 121, cooperate first brake piece 140 and elastic component 150 again, can make stirring piece 130 when sliding along first via hole 121, can realize locking and unblock to the current angle of rotating piece 120, after rotating piece 120 is locked, rotating piece 120 then can not continue to rotate, and it can keep at current rotation angle, only can continue to rotate after rotating piece 120 is unblocked.

Specifically, in the present embodiment, the first braking member 140 is located in the housing 110, and the first braking member 140 is fixed on the stirring member 130, and the first braking member 140 can move synchronously along the axis direction of the first via hole 121 along with the stirring member 130. One end of the elastic member 150 is fixedly connected with the toggle member 130, and the other end of the elastic member 150 is connected with the rotating member 120. When an external force for sliding the toggle member 130 along the first through hole 121 is not applied to the toggle member 130, the elastic member 150 is configured to drive the toggle member 130 to slide along the axial direction of the first through hole 121 by elastic force, and compress the first braking member 140 on the housing 110, when a friction force generated between the first braking member 140 and the housing 110 is greater than a driving force generated by rotation of the rotating member 120, the first braking member 140 is matched with the elastic member 150 to lock the rotating member 120 in a current position, and the current position may be any angular position to which the rotating member 120 rotates after the toggle member 130 is driven, that is, when the first braking member 140 is adhered to the housing 110, the elastic member 150 still has elastic force to provide a pre-tightening force to the first braking member 140. After locking the rotation member 120, no medical personnel is required to manually maintain the position of the toggle member 130. When an external force is applied to the toggle member 130 to enable the toggle member 130 to slide along the first through hole 121, the toggle member 130 moves, the first braking member 140 is separated from the housing 110, the elastic member 150 generates elastic force due to deformation in the process, and after the applied external force is removed, the elastic member 150 drives the toggle member 130 to restore to the original position under the action of the elastic force, wherein the original position refers to the position where the toggle member 130 is located when the first braking member 140 is pressed on the housing 110. And, after the first stopper 140 is separated from the housing 110, the rotation member 120 is unlocked, and at this time, the rotation of the rotation member 120 can be controlled by the toggle member 130.

It should be noted that, in the unlocking and locking processes of the rotating member 120, the stirring member 130 needs to be disposed in the first through hole 121, so that the stirring member 130 can drive the rotating member 120 to rotate and drive the rotating member 120 to stop. Also, the elastic member 150 may be connected between the toggle member 130 and the housing 110 in addition to being connected between the toggle member 130 and the rotary member 120 in some other embodiments.

In this embodiment, the stirring member 130 is slidably connected to the first through hole 121 of the rotating member 120, so that the stirring member 130 can slide along the axial direction of the first through hole 121, and the elastic member 150 connected between the rotating member 120 and the stirring member 130 causes the elastic member 150 to deform and generate elastic force during sliding of the stirring member 130, and the first braking member 140 fixed on the stirring member 130 compresses the housing 110 under the action of the elastic force to lock the rotating member 120.

Further, in the present embodiment, the first through hole 121 passes through the rotating member 120 along the radial direction of the rotating member 120, and the axis of the first through hole 121 perpendicularly intersects with the rotation center line of the rotating shaft, so that the rotating member 120 passing through the first through hole 121 also passes through the rotating member 120 from the radial direction, and when the stirring member 130 drives the rotating member 120 to rotate, the rotation angle of the stirring member 130 is the same as the rotation angle of the rotating member 120. By means of the arrangement, on one hand, medical staff can control the rotating angle of the stirring piece 130 more accurately according to the angle required by the active bending section of the endoscope, and on the other hand, the fulcrum of the stirring piece 130 driving rotating piece 120 coincides with the rotating center of the rotating piece 120, so that labor can be saved in the rotating process of the rotating piece 120.

It should be noted that, in some other embodiments, the first through hole 121 may also penetrate the rotating member 120 in a direction parallel to the axial direction of the rotating member 120, that is, the first through hole 121 is disposed at an eccentric position of the rotating member 120, so that the locking of the rotating member 120 may also be achieved by the first brake member 140 and the elastic member 150.

Further, in order to facilitate the medical staff operating the toggle member 130 to unlock and lock the rotating member 120, in this embodiment, the pressing direction is set as the unlocking direction of the rotating member 120, and the restoring direction opposite to the pressing direction is set as the locking direction of the rotating member 120. The pressing direction is a direction in which the distal end of the stirring member 130 is located along the axial direction of the first via hole 121 toward the proximal end of the stirring member 130, and the restoring direction is a restoring direction in which the stirring member 130 is in a restoring state when the proximal end of the stirring member 130 moves along the axial direction of the first via hole 121 toward the distal end of the stirring member 130. By means of the arrangement, on the one hand, medical staff can unlock the rotating member 120 by pressing the stirring member 130, and the rotation angle of the unlocked rotating member 120 can be adjusted by moving the stirring member 130; after the rotating member 120 is rotated to a required angle, the stirring member 130 is released to lock the rotating member 120, so that after the rotating member 120 is rotated to the required angle, the position of the stirring member 130 is not required to be manually maintained by medical staff, and the operation intensity of the medical staff is reduced; on the other hand, the locking, unlocking and rotation of the rotating member 120 are realized by the toggle member 130, so that when the rotation angle of the rotating member 120 is adjusted, medical staff only needs to hold the endoscope handle 100 by one hand, and the locking, unlocking and rotation of the rotating member 120 are realized by operating the toggle rod by one finger, thereby greatly reducing the operation difficulty of the medical staff. Of course, the endoscope handle 100 may be configured to be pulled up by the pulling-up toggle 130 to unlock the rotator 120 without considering the convenience of unlocking.

Further, in the present embodiment, the housing 110 is provided with the second braking member 160, and the second braking member 160 can cooperate with the first braking member 140 to generate a larger braking force. The second stopper 160 is provided at a position where the first stopper 140 is pressed against the housing 110, so that the second stopper 160 is engaged with the first stopper 140 instead of the housing 110. When the rotating member 120 is locked, the first stopper 140 is pressed against the second stopper 160. The second stopper 160 is generally formed of a material or shape capable of generating a greater friction with the first stopper 140 to prevent the occurrence of unstable locking.

The first through hole 121 is located between the proximal end of the toggle member 130 and the first stopper 140 such that the first stopper 140 can move in a pressing direction and separate from the housing 110 when the toggle member 130 is pressed. In some other embodiments, the first detent 140 may also be fixed to the proximal end of the toggle member 130, with the first via 121 located between the distal end of the toggle member 130 and the first detent 140.

In this embodiment, the first braking member 140 and the second braking member 160 are both made of a damping material with high damping characteristics.

Further, in the present embodiment, the first braking member 140 is detachably connected to the toggle member 130. So that the first brake 140 can be easily replaced after wear. In addition, the second brake 160 in the present embodiment is detachably connected to the housing 110, so that the second brake 160 can be replaced conveniently even after being worn. The first detent 140 is detachably connected to the toggle 130 and the second detent 160 is detachably connected to the housing 110, including but not limited to a threaded connection, a snap-fit connection, or a bayonet connection.

It should be noted that, without considering the convenience of replacing the first brake member 140 and/or the second stop member, the first brake member 140 and the toggle member 130 and/or the second brake member 160 and the housing 110 may be connected by integrally molding or permanently and fixedly connected by welding, bonding, or the like.

Further, in the present embodiment, the second stop member is annular, the second brake member 160 is coaxially disposed with the rotating shaft 124 of the rotating member 120, and the second stop member is sleeved outside the rotating shaft 124 of the rotating member 120, and since the first through hole 121 passes through the rotating member 120 along the radial direction of the rotating member 120, and the axis of the first through hole 121 intersects with the rotation center line of the rotating member 120, the first brake member 140 can abut against the second brake member 160 no matter the rotating member 120 rotates to any angle. By the arrangement, the material consumption of the second braking piece 160 and the coverage area of the second braking piece 160 can be greatly reduced, and the position of the second braking piece 160 is convenient to install and fix. If the second braking member 160 is disposed at other positions of the housing 110, the sliding direction of the first braking member 140 will be changed correspondingly after the rotating member 120 rotates by a certain angle, so that the required second braking member 160 needs to cover a larger area of the housing 110, which affects the arrangement of other components in the housing 110.

Further, in the present embodiment, in order to fix the elastic member 150 conveniently, the stopper 122 is disposed on the rotating member 120 in the present embodiment, and two ends of the elastic member 150 are connected to the stopper 122 and the first brake member 140, respectively. In addition, the elastic member 150 is a spring in the present embodiment, the spring is sleeved outside the toggle member 130, and the spring passes through the first via hole 121. The spring is adopted to enable the deformation direction of the elastic piece 150 to be the axial direction deformation, the deformation direction is controllable, and the occupied space of the deformation is small. Of course, in some other embodiments, the elastic member 150 may also use a spring plate or other members with elastic function.

Further, a second through hole 123 is formed in the stop portion 122, the second through hole 123 penetrates through the stop portion 122, the second through hole 123 and the first through hole 121 are coaxially arranged, the poking member 130 penetrates through the second through hole 123, and the inner wall of the second through hole 123 is matched with the poking member 130 in size so as to avoid shaking between the waveguide member and the rotating member 120. Meanwhile, the second through hole 123 can increase the connection position of the stirring member 130 and the rotating member 120, so that the connection stability between the stirring member 130 and the rotating member 120 is better.

It should be noted that, in the present embodiment, the entire body portion of the stirring member 130 is in a round bar shape, so as to facilitate connection between the stirring member 130 and the first via hole 121 and/or the second via hole 123. In some other embodiments, the striking member 130 has at least a portion with a straight rod shape, so that the striking member 130 can slide linearly with the rotating member 120 through the straight rod-shaped portion.

Further, in this embodiment, the housing 110 is provided with a guiding groove 111, the width of the guiding groove 111 is adapted to the width of the stirring member 130, the proximal end of the stirring member 130 passes through the guiding groove 111, and the length of the guiding groove 111 is adapted to the rotation angle of the rotating member 120, so that the stirring member 130 can swing in the guiding groove 111 along the length direction of the guiding groove 111, and the rotating member 120 is controlled to rotate. The guide groove 111 can play a limiting role on the swing angle of the poking piece 130, correspondingly controls the rotation angle of the rotating piece 120, and avoids damage to the free bending section of the endoscope or damage to the traction wire caused by overlarge rotation angle of the rotating piece 120.

In addition, as shown in fig. 6, the present embodiment also provides another braking mode of the first braking member and the second braking member, in this embodiment, the first braking member 140 is provided with a first tooth-shaped portion 141, the second braking member 160 is provided with a second tooth-shaped portion 161 engaged with the first tooth-shaped portion 141, after the first braking member 140 is pressed against the second braking member 160, the first tooth-shaped portion 141 is engaged with the second tooth-shaped portion 161, and the locking effect on the rotating member 120 is enhanced by the engagement of the first tooth-shaped portion 141 and the second tooth-shaped portion 161.

After the first tooth 141 and the second tooth 161 are provided, it is possible to rotate whether the first brake 140 and the second brake 160 are provided as damping members according to actual conditions.
